AUTO-LOCKING DEVICE.

Application filed September 28, 1920.

To all whom it may concern:

Be it known that 1, Greece Zrnzsn, a citizen or the United States, residing at Bath, in the county of Steuben and gtate of New York, have invented a new and useful Auto- Locking Device, of which the "following is a specification.

It is the object of this invention to pro vlde novel means whereby the lighting and ignition circuits of an automobile may be malntained open, against unauthorized e1 forts to close the circuits and start the car.

llt is within the province of the disclosure to improve generally and to enhance the utility of devices oi": that type to which the invention appertains.

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention. 7

In the accompanying drawings Figure 1 shows in elevation, a device constructed in accordance with the invention;

Fig. 2 is a diagram illustrating the invention;

Fig. 3 is a cross section taken through the slide;

Fig. 4 is a iragmental plan showing a portion of the slide.

In carrying out the invention, there is provided a support or casing 1, which, preferably, is mounted on the instrument board of a motor car. The support 1 carries a rotatable lighting switch 2 of the common sort, interposed in the lighting circuit 3. A. rotatable key actuated ignition switch a is supplied, the switch 4t being interposed in the ignition circuit 5. The key actuated switch 4 is operatively connected to an arm 6 mounted to swing parallel to the support or casing 1.

The lower end of the arm 6 is pivotally connected to an operating rod 7, the casing or support 1 carrying an insulating guard 8 extended between the rod 7 and the arm 6 at the point of pivotal connection between these parts. The operating rod 7 is pivoted to one end oi. a first lever 9, iulcrumed intermediate its ends, as shown at 10, on the S ecification of Letters Patent.

support 1. Upward and longitudinal movement of the rod 7 is limited by a stop lug 11 carried by an insulating plate 12 mounted 1. A plunger 15 is mounted for right line reciprocation in the casing of the permutation lock 14, the construction being such that when a given combination is set up in the permutation lock 14, the plunger 15 can slide endwise, whereas, when the predetermined combination has not been set up, the plunger 15 cannot slide endwise. The plunger is united to the first lever 9 by means of a pin and slot connection 16.

An insulating plate 17 is mounted on the support 1 and is provided with guides 18, between which a slide 19 is mounted for longitudinal reciprocation. The slide 19 is provided with conducting bridges 20 and 21. The bridges 20 are adapted to move into and out of contact with brushes 22 on the plate 17, the bridges 21 being adapted to move into and out of contact with brushes 23 on the plate 17. Insulating strips 24 are secured to the slide 19, on each side of each bridge 2120. The numeral 25 designates a second lever, fulcrumed intermediate its ends, as shown at 26, on the plate 17. The lever 25 is supplied at its ends with slots 27, one slot receiving a pin 28 and the operating rod 7, the other slot receiving a pin 30 and the slide 19, the operating rod 7 being cut away as indicated at 29, for the restriction of one end of the lever 25.

hen a predetermined combination has been set up in permutation lock 1 4:, the plunger 15 can slide endwise, but, untll such a combination has been set up, plunger 15 cannot slide endwise. This feature renders the entire device subject to the will of an operator, and unless the predetermined combination is known, the plunger 15 cannot slide enclwise and it will be impossible to close the ignition and lighting circuit; Assuming, however, that the combination has been set off and that the plunger 15 can slide endwise, the ignition switch 4: may be rotated, thereby closing the ignition circuit 5. The arm 6 is swung by the action of the switch 1 and longitudinal movement is imparted to the rod 7, motion being transmitted from the rod 7 to the plunger 15 by way of the lever 9. From the operatinto contact with the brushes 23, and the ignition circuit 5 will be closed completely. Similarly, when the bridges 20 come into contact with the brushes 22, the lighting circuit'3 will be closed adjacent to the slide 19, it being possible to close the lighting circuit completely, and to light the car, by a manipulation of the lighting switch 2. Having thus set forth the operationoi the device, it will be clear that, unless the proper combination has been set up in the permutation lock 14, the plunger-i5 will not be permitted to slide under the impulse originating in the ignition switch l and, consequently,the ignition circuit and the lightin circuit cannot be closed.

having thus described the invention, what is claimed is r 1. In a device of the class described, a pair of movable members; means for connecting said members operatively; permutation mechanism controlling the movement of one of said members; a circuit; means carried by the other of said members for opening and closing the circuit; and means for operating the first specified one of said members, said means including a. switch interposed in the circuit.

2. In a device of the class described, a pair of approximately parallel members mounted for longitudinal movement; means 7 carried by one of said members for opening and closing a circuit; a lever fulcrumed intermediate its ends and connected with said members; permutation mechanism controlling the movement of the other of said members; and means for operating that one of said members wherewit-h the permutation mechanism coacts.

3. In a device of the class described, a pa1r of members mounted for longitudinal movement; means carried by one of said members for opening and closing a circuit;

an operating connection between said members; a permutation lock; a plunger slidable in the lock and controlled by the lock; a lever fulcrumed intermediate its ends and connected pivotally to the plunger and to the other of said members; and means for operating the other of said members.

7 4. Ina device of the class described a pair of members mounted for longitudinal movement ;,means forconnecting said members; means carried by one of said members for opening and closing a circuit; a rotary switch including an arm pivoted to the other of said members; and permutation means for controlling the movement of the other 01" said members.

5. In a device of the class described, a pair 7 pivotally connected with the other end of.

the lever; and a permutation mechanism wherein the plunger slides, the permutation mechanism controlling thebperation of the plunger.

In testimony that I claim the foregoing i as my own, I have hereto affixed my signature in the presence of two witnesses.

GEORGE ZINZEL.
